This paper presents a hierarchical internet model suitable for simulating the impact of a localized physical disaster on the Internet within a typical metropolitan area. This first order model reports internet availability as the ratio of offered to car-ried traffic. We compute the carried traffic by examining the fraction of offered network traffic which flows through potentially impaired network entities. The impact of a physical disruption on a network entity reduces the carried traffic by the fraction of traffic which passes through that entity. The model is fully parameterized with respect to application properties (locality, latency, bandwidth, etc.) and connections to other infrastructure models (electric, phone, etc.). We also present a simplified system dynamics representation of this model using Vensim.
